Icons in email subjects

From time to time I receive some emails with nice icons in the subject and I was curious about how they are doing it. Maybe I am the last at the web to found out, but now I did.

It’s done by so called emoji icons which are included in the UTF-8 character set.

At Wikipedia is a list of miscellaneous symbols and at I found a good “cheat sheet”. On usage and compatibility I suggest as well the article of René from Optivo in Berlin.
